Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Nut Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Beat the butter and sugar together until creamy.
Add the water and flour, stirring until smooth.
Make and bake the batter
Incorporate half of the well-beaten egg whites.
Fold in the nuts, then add the remaining egg whites and baking powder.
Pour the batter into square flat tins lined with buttered paper, filling to a depth of 3 inches.
Bake for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give a tender, rich crumb.
- Egg whites
- Whipped to foam, they add lift and structure to the batter.
- Flour
- Forms the structure of the cake as its proteins set in the oven.
- Sugar
- Sweetens the cake and helps the butter hold air when creamed.
- Nut kernels
- Add texture, richness and fat, giving the cake body.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
The step that matters
Folding in the egg whites. Egg whites hold air only when whipped and gently folded. Stirring or overmixing deflates the foam, leaving a denser cake with less rise.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
